Engineering Selection Recommendations

The Weidmüller 2442950000 is the direct functional equivalent for the obsolete 1231660000. Both components share identical electrical specifications, mechanical dimensions, and termination characteristics within the Omnimate BC series. The 2442950000 holds active product status, ensuring ongoing availability and supply chain continuity.

Key differentiators are cosmetic and operational:

Housing Color: The substitute features orange housing versus black on the original part. This distinction is aesthetic and does not affect electrical or mechanical performance.
Actuation Feature: The 2442950000 includes push button actuation in addition to ejector latches, providing enhanced connector release capability without compromising compatibility.
Compliance Certifications: Both parts maintain RoHS compliance and UL94 V-0 flammability ratings. The substitute carries identical electrical certifications under both IEC and UL standards.

Selection of the 2442950000 is appropriate for direct replacement applications where the 1231660000 is no longer procurable.

Frequently Asked Questions (FAQ)

Q: Can the 2442950000 directly replace the 1231660000 in existing installations?

A: Yes. Both components are mechanically and electrically equivalent within the Omnimate BC series. They share identical pitch (0.150"), position count (18), wire gauge compatibility (16-26 AWG), and electrical ratings (IEC 17.5A/320V, UL 10A/300V). The housing color and push button actuation feature on the substitute do not affect functional compatibility.

Q: What is the significance of the product status change from Obsolete to Active?

A: The 1231660000 is classified as obsolete, indicating discontinued manufacturing and limited remaining inventory (753 pcs). The 2442950000 maintains active status with current production and adequate stock levels (814 pcs), ensuring reliable procurement for new designs and ongoing maintenance requirements.

Q: Are there any electrical performance differences between these parts?

A: No. Both components operate at identical IEC ratings (17.5A/320V) and UL ratings (10A/300V). Operating temperature range (-50°C to 120°C), contact material (copper alloy), and termination method (screwless push-in spring) are equivalent across both parts.

Q: Does the orange housing color of the 2442950000 affect system compatibility?

A: No. Housing color is a cosmetic distinction and does not impact electrical performance, mechanical fit, or functional operation. Color coding may be used for visual identification in multi-connector applications but does not alter substitution eligibility.

Q: What packaging considerations apply to the 2442950000?

A: The substitute is supplied in bulk packaging, whereas the original part number does not specify packaging format. Bulk packaging is standard for terminal block components and does not affect component performance or installation procedures.
